“…The structural parameters such as the hopping lengths for A-site (L A ) and B-site (L B ) were calculated using standard equations ( 6) and (7), and the ionic radii (r A and r B ) were determined considering the oxygen positional parameter 'µ' with the standard value of 0.0375 nm and using the radius of oxygen anions r o of 0.135nm [16]. The tetrahedral ionic radii (A-site) and octahedral ionic radii (B-site) were determined by equations ( 8) and (9), respectively [17].…”

“…Various literature deals with synthesizing Co ferrite by the co-precipitation method, but nearly no study deals with Co ferrite properties due to substitution by Cs. Houshiar et al [7], prepared Co ferrite nanoparticles by co-precipitation method where metal chlorides as starting materials and sodium hydroxide are used as a precipitating agent. The obtained sample was heated at 600 o C for 10h.…”

The effect of substitution ferrite by previously not used elements to control magnetic properties is of great interest to researchers. This study illustrates the effect of low substitution of Cs, with molar ratios of y of 0.0, 0.05, 0.15, and 0.25 on the structural and magnetic properties of CsyCo1-0.5yFe2O4nanoparticles. The synthesizing method was the co-precipitation method. The metal chlorides were used to perform the reaction in the distilled water using NaOH to reach a pH of 10. The X-ray diffraction, Field Emission Scanning Electron Microscopy, Electron Dispersive X-ray and Vibrating Sample Magnetometry analyses were conducted for all samples. All samples had the patternsof the spinel structure coincide to a high degree with the Co ferrite pattern. There was a general increase in the lattice constant with the increase in the Cs content, while the crystallite size decreased from about 18 to 12.2 nm as the molar ratio increased from 0 to 0.25. The Electron Microscopy investigation showed that all samples owing spherical nanoparticles with no other shapes. The average particle sizes were between 40 to 60nm, which increased Cs1+content. The magnetic parameters mainly showed a relatively high coercivity (wide loops) and a decrease in magnetization saturation (down to 50.43emu/g), crystalline anisotropic constant, and thesquareness ratio
